I'm thinking the pellets are to small so its feeding way to many at a shot. Its easy enough to pick up a few bag's of another brand of pellets. Hopefully Sysko will chime in on this post. He seems to be the guy to talk to about stuff on the electronic side of thing's if its a control board issue. Have you considered giving Englander a call? there help desk is pretty good.Yeah is something new. We got it used last year and worked ok. The brand of pellets we have a smaller. It is a different brand than last year. Nobody local carries our old brand. Last night when I went to bed the flame was crazy and the hopper handles were even hot. During the night when I checked it the flame looked good and the handles were cool. However when I got up this morning and the flame was all over again and the hopper handles were hot again.
